范围验证ASP.net [英] Range Validation ASP.net

问题描述

亲爱的所有



我是这个论坛的新手，这是我的第一个疑问。



我在lang VB 后面的 ASP.NET （ visual studio ）代码中有一个小表格。



在此表格上还有两个txtbox和其他控件。



设 txt1 & txt2 ，两者都包含日期

我需要验证的是;



txt1< = txt2< =今天的



帮助

解决方案

使用此： -

 function BirthdayValidator（ txtDOB）
 {
  var  userDate = txtDOB。 value  
 < span class =code-keyword> var  today =  new  Date（）;  //  获取今天的日期 
 uDt = userDate.split（  /）;  //  获取用户日期 
  var  uDate =  new 日期（uDt [ 2 ]，uDt [ 1 ]  -   1 ，uDt [ 0 ]）; 
  if （uDate> today）
 {
 alert（ '日期应小于今天的日期。）; 
 txtDOB。 value  =  ; 
 txtDOB.focus（）; 
  return   false ; 
} 
} 

你可以使用asp：CompareValidator。



类似



1.

< asp：comparevalidator id =   compvalidDtGft runat =   server cssclass =   red forecolor =   controltovalidate =   txt2 controltocompare =   txt1 xmlns：asp =  ＃unknown >  
 ErrorMessage =  选择的日期不能大于第一个日期。 Operator =   LessThanEqual Type =  日期 
显示=  动态 >  < /   asp：comparevalidator  >  

in除此之外



2.

< asp：comparevalidator id =   CompareValidator1 runat =   server controltovalidate =   txt2 xmlns：asp =  ＃unknown >  
 
 ErrorMessage =   CompareValidator Operator =   GreaterThanEqual Type =  日期 >  < /   asp：comparevalidator  >  

并尝试把它放在page_load事件上

  protected   void  Page_Load（ object  sender，EventArgs e）
 
 {
 
 CompareValidator1。 ValueToCompare = DateTime.Now.ToShortDateString（）; 
 
} 

或尝试



2.

< asp：comparevalidator id =   CompareValidator1 runat =   server  controltovalidate =   txt2 valuetocompare =   <％= DateTime.Now.ToShortDateString（）％> xmlns：asp =  ＃unknown >  
 
 ErrorMessage =   CompareValidator运算符=   GreaterThanEqual类型=  日期 >  < /   asp：comparevalidator  >  

如果所有这些都不起作用尝试编写自定义验证器

< asp：RangeValidator ID =   valrDate runat = < span class =code-string>  server ControlToValidate =   txtDob MinimumValue =   01/01/1940 
 MaximumValue =   31/12/1994 Type =  日期 Text =  此日期不能是出生日期 
显示=  动态字体大小=   Smaller ValidationGroup =  提交 /> 

Dear All

I''m new to this forum and this one is my very first query.

I''ve a small form in ASP.NET (visual studio) code behind lang VB.

On this form there are two txtboxes and other controls too.

Let txt1 & txt2, both contain Date
What I need to validate is;

txt1 <= txt2 <= Today''s

Help

解决方案

Use this:-

function BirthdayValidator(txtDOB)
{
    var userDate = txtDOB.value
    var today = new Date();            // get today's date
    uDt = userDate.split("/");          //get user date
    var uDate = new Date(uDt[2], uDt[1] - 1, uDt[0]);
    if (uDate>today)
    {
        alert("'Date Should be less than Today's Date.");
        txtDOB.value="";
        txtDOB.focus();
        return false;
    }
}

you can use an asp:CompareValidator.

as like

1.

<asp:comparevalidator id="compvalidDtGft" runat="server" cssclass="red" forecolor=" " controltovalidate="txt2" controltocompare="txt1" xmlns:asp="#unknown">
                                          ErrorMessage="Date selected cannot be greater than first date." Operator="LessThanEqual" Type="Date"
                                          Display="Dynamic"></asp:comparevalidator>

and in addition to this

2.

<asp:comparevalidator id="CompareValidator1" runat="server" controltovalidate="txt2" xmlns:asp="#unknown">

ErrorMessage="CompareValidator" Operator="GreaterThanEqual" Type="Date"></asp:comparevalidator>

And Try to put this on page_load event

protected void Page_Load(object sender, EventArgs e)

{

CompareValidator1.ValueToCompare = DateTime.Now.ToShortDateString();

}

or try

2.

<asp:comparevalidator id="CompareValidator1" runat="server" controltovalidate="txt2" valuetocompare="<%= DateTime.Now.ToShortDateString() %>" xmlns:asp="#unknown">

ErrorMessage="CompareValidator" Operator="GreaterThanEqual" Type="Date"></asp:comparevalidator>

IF all these doesn''t work try to write a custom validator

<asp:RangeValidator ID="valrDate" runat="server" ControlToValidate="txtDob" MinimumValue="01/01/1940"
                       MaximumValue="31/12/1994" Type="Date" Text="This Date Could not be a Birth Date"
                       Display="Dynamic" Font-Size="Smaller" ValidationGroup="Submit" />
